Back-End-of-Line Compatible Transistors for Monolithic 3-D Integration

The manufacturers of high-performance logic have been ardent champions of Moore's Law, which has resulted in exponential increase in aerial transistor density to 100 million transistors per square millimeter of silicon real estate. However, it is the memory chip makers who have taken the first step toward escaping the confines of scaling within the horizontal plane and have embraced the vertical or the third dimension. The dynamic random access...
